I want to do query elastic search with bands(example .. age band {10-20,20-30,etc}). How can i do this .
i have tried painless scripting: by which i am able to create a new field. But i want to do group by , count , sum like SQL operations on ES query result. Please guide me with example .

There is Range Query | Elasticsearch Guide [6.6] | Elastic which should do what you want?

Can you elaborate more on what you are trying here. Sharing example code if you have it would be super handy.
